In this work, electrochemical removal of hydrocortisone, a steroid hormone, from water using aluminum electrodes was investigated. The effects of many experimental parameters such as current density, electrolysis time, initial concentration of hydrocortisone, initial pH, electrolyte type and concentration, and distance between electrodes were studied. Moreover, the sludge formed was characteriz...

the electrochemical behavior of nifedipine (i), nitrendipine(ii) and their photodegradation products has been studied by employing electrochemical techniques in chloroform and in 1:4 mixture of chloroform-isopropanol using piperidinium perchlorate (ppc) as supporting electrolyte. it has been shown that i and ii undergo in a 4e, 4h+ irreversible reduction reaction, while the reduction product, p...

the performance of a plug flow electrocoagulation reactor for the treatment of cattle abattoir(slaughterhouse) wastewater was investigated. a cylindrical iron reactor was operated as a cathode at arecycling batch mode while three iron rods located at the center of the reactor were used as an anode. theeffects of different parameters, including the current density, the supporting electrolyte dos...

All-solid-state lithium-ion batteries using Li+-ion conducting ceramic electrolytes have been focused on as attractive future batteries for electric vehicles and renewable energy conversion systems because high safety can be realized due to non-flammability of ceramic electrolytes. In addition, a higher volumetric energy density than that of current lithium-ion batteries is expected since the a...

The electrochemical reduction of zanosar was investigated systematically by direct current polarography, cyclic voltammetry, and differential pulse polarography (DPP). A simple DPP technique was proposed for the direct quantitative determination of anticancer drug zanosar in pharmaceutical formulation and spiked human urine samples for the first time. The reduction potential was -0.28 V versus ...

This paper describes a novel electrochemical method for the determination of Sudan I in food samples based on the electrochemical catalytic activity of graphene modified glassy carbon electrode (GMGCE) and the enhancement effect of an anionic surfactant: sodium dodecyl sulphonate (SDS). Using pH 6.0 phosphate buffer solution (PBS) as supporting electrolyte and in the presence of 1.5 × 10(-4)mol...

A new method for the determination of the diffusion coefficients of both the substrate, DS, and the product, DP, of an electrode process has been developed. The method proposed is based on the analysis of the transient currents and can be applied to some reactions of the type SzS = PzP + ne and, in contrast to the concept based on the steady-state current, to any ratio of the concentrations of ...

The present work has been carried out to study the mechanism of electrochemical degradation of Congo red dye. Electrolysis has been carried out in a single-chamber electrochemical cell having graphite anode and platinum cathode in the presence of KCl as supporting electrolyte under amperostatic conditions. The potential across the electrodes has been adjusted so that a constant 30 mA current pa...
